As one of the core ocean shipping routes for Sino-US trade, Shanghai to Los Angeles ocean freight carries a large volume of cross-border cargo transportation demand. However, the persistent congestion at the Port of Long Beach (LB Port) has seriously affected the efficiency of cargo devanning, becoming a core pain point for freight forwarders worldwide. This article will combine the latest port data and practical experience to provide flexible routing solutions for freight forwarders and solve the problem of devanning inefficiency.

Why Does LB Port Congestion Become an "Efficiency Bottleneck" for Shanghai to Los Angeles Ocean Freight?

As a core supporting port of the Port of Los Angeles, LB Port is only 10 kilometers away from the Port of Los Angeles. Together, they handle 40% of the total US inbound maritime container volume and are one of the main Ports of Destination (POD) for Shanghai to Los Angeles ocean freight. Its congestion directly leads to delays in the entire process of cargo unloading, devanning, and container pickup, significantly increasing the operating costs of freight forwarders and even resulting in additional expenses such as Demurrage and Detention.

According to the latest data from the official website of the Port of Los Angeles in April 2026, the average daily waiting time for ships to berth at LB Port is as long as 11-13 days, an increase of 4 days compared with the same period in 2025; the port container backlog has increased by 21% year-on-year, and the freight yards and Container Yards (CY) in Southern California are already operating at full capacity, with devanning efficiency dropping by more than 45% compared with normal periods.

The United Nations Conference on Trade and Development (UNCTAD) pointed out in the latest version of the "Global Maritime Transport Development Report" released in April 2026 that the operational efficiency of ports on the US West Coast is relatively low. Asian ports take an average of 27 seconds to lift a Twenty-foot Equivalent Unit (TEU), while North American ports take 76 seconds. This efficiency gap has further exacerbated the congestion at LB Port and directly affected the overall timeliness and stability of Shanghai to Los Angeles ocean freight.

Freight forwarders need to note that LB Port congestion is not a short-term phenomenon. It is caused by multiple overlapping issues such as aging terminal equipment, a shortage of truck drivers, and insufficient liquidity of container chassis. According to the latest report from Dealmoon in 2026, the current shortage of truck drivers in the United States has reached 175,000, and this structural shortage is difficult to completely alleviate in the short term. Therefore, relying on a single LB Port unloading route will inevitably lead to the loss of cargo timeliness and affect customer trust in cooperation.

What Are the Core Routes for Shanghai to Los Angeles Ocean Freight? What Are the Differences in Devanning Efficiency Between Each Route?

The core routes for Shanghai to Los Angeles ocean freight are mainly divided into three categories: direct LB Port route, direct Port of Los Angeles (LA Port) route, and transshipment route. Different routes have significant differences in unloading efficiency and devanning timeliness. Freight forwarders need to choose reasonably based on customer timeliness requirements and cost budgets.

The recommended approach is that when undertaking Shanghai to Los Angeles ocean freight business, freight forwarders should not be limited to a single route. Instead, they should flexibly combine the three types of routes according to customer timeliness requirements, cargo value, and cost budgets. For high-timeliness and high-value cargo, priority should be given to the direct LA Port route; for cargo with low timeliness requirements and cost sensitivity, the transshipment route can be selected; for cargo with large volume that needs flexible deployment, part of the LB Port route can be reserved, and the direct LA Port or transshipment route can be used as a backup.

How to Avoid LB Port Congestion and Improve Devanning Efficiency Through Flexible Routing Planning?

The core of flexible routing planning is "advance prediction, multiple backup plans, and full-process tracking". Combined with the route characteristics after departing from Shanghai Port (Port of Loading, POL) and the local port conditions in Los Angeles, freight forwarders can follow the following steps to maximize devanning efficiency.

Step 1: Predict LB Port Congestion in Advance and Choose Routes Reasonably. Freight forwarders need to check the ship waiting time and container backlog data released on the official website of LB Port daily, and refer to the China Import and Export Container Freight Index (CICFI) and congestion warning report for the US West Route released by the Shanghai Shipping Exchange on April 1, 2026, to predict the port congestion trend in the next 1-2 weeks. According to data from the Shanghai Shipping Exchange, the US West Route index in April 2026 increased by 6.0% compared with March, showing an obvious trend of increasing congestion. At this time, freight forwarders should take the initiative to reduce the number of bookings for the direct LB Port route and increase the reserve of direct LA Port routes and transshipment routes.

Step 2: Cooperate with High-Quality Shipping Companies and Lock in Exclusive Terminal Resources. Different shipping companies have significant differences in terminal resources at Los Angeles ports. For example, Matson Clipper has a dedicated terminal at LB Port, which can achieve "on-arrival unloading", and its devanning timeliness is 3-4 days faster than that of ordinary shipping companies; COSCO Shipping, CMA CGM, and other shipping companies have dedicated terminals at LA Port, with stable devanning efficiency. Freight forwarders need to note that they should give priority to cooperating with shipping companies that have exclusive terminal resources, sign long-term cooperation agreements, lock in container space and unloading priority, and avoid timeliness delays caused by insufficient terminal resources.

Step 3: Optimize Transshipment Route Design and Reduce Transshipment Link Loss. If choosing a transshipment route, freight forwarders should give priority to the Port of Oakland as the transshipment port. According to the latest data from the Shanghai Shipping Exchange, the devanning efficiency of the Port of Oakland in the second quarter of 2026 is 38% higher than that of LB Port, and the transshipment connection process is mature. At the same time, it is necessary to connect with the transshipment port agent in advance to clarify the unloading and transshipment time of transshipment cargo, so as to avoid additional delays caused by poor transshipment connection; it is recommended to choose the direct transshipment route "Shanghai-Oakland-Los Angeles" to reduce the number of intermediate calls and shorten the transshipment timeliness.

Step 4: Complete Customs Clearance Procedures in Advance to "Speed Up" the Devanning Process. Devanning efficiency depends not only on port congestion but also on the progress of customs clearance. After the cargo departs from Shanghai Port, freight forwarders should immediately submit customs clearance documents to US Customs, including Commercial Invoice (CI), Packing List (PL), Bill of Lading (B/L), AMS declaration form, etc., and complete the Importer Security Filing (ISF) declaration to avoid cargo detention caused by missing or incorrect customs clearance documents. A common misunderstanding is that some freight forwarders only start handling customs clearance procedures after the cargo arrives at the port, leading to customs clearance delays and thus affecting the devanning progress.

Step 5: Establish Routing Emergency Plans to Respond to Sudden Congestion. Freight forwarders need to establish at least 2 sets of emergency routing plans for the Shanghai to Los Angeles ocean freight route. For example, if there is sudden extreme congestion at LB Port (according to the monitoring of Lloyd's List on March 22, 2026, the number of ships waiting at anchor at LA and LB Ports has surged to 45, with a congestion rate rising to 18%), the cargo originally destined for direct LB Port can be temporarily adjusted to unload at LA Port; if the container space at LA Port is tight, it can be urgently switched to the Oakland Port transshipment route. At the same time, it is necessary to maintain real-time communication with shipping companies and local agents in Los Angeles to timely obtain port dynamics and quickly adjust routing plans.

What Other Details Can Freight Forwarders Pay Attention to to Improve Devanning Efficiency in Shanghai to Los Angeles Ocean Freight?

In addition to flexible routing planning, freight forwarders can further improve devanning efficiency, reduce operational risks, and enhance customer satisfaction by paying attention to the following details throughout the entire operation process.

Detail 1: Standardize Cargo Packing and Declaration Processes to Avoid Inspection Delays

According to authoritative industry data, about 30% of devanning delays are caused by incorrect cargo declaration or non-standard packing. Freight forwarders need to note that they should strictly review cargo information to ensure the accuracy of declared data such as commodity name, HS code, weight, and volume, and eliminate false declarations; for sensitive cargo such as those with electricity or magnetism, it is necessary to declare in advance and provide relevant test reports to avoid devanning inspection delays caused by inconsistent cargo attributes. At the same time, guide shippers to standardize packing, reasonably distribute cargo weight, and affix standard cargo labels to avoid devanning difficulties caused by overpacking, center of gravity deviation, or missing labels.

Detail 2: Select High-Quality Local Agents in Los Angeles to Improve Terminal Operation Efficiency

The operational capability of local agents directly affects the efficiency of devanning and container pickup. Freight forwarders should select agents with rich operational experience, good relations with Los Angeles port terminals, and professional customs clearance capabilities to ensure that after the cargo arrives at the port, it can quickly connect with unloading and devanning matters and timely handle sudden problems (such as inspection, demurrage, container roll-over, etc.). The recommended approach is to conduct on-site inspections of the local agent's office and operation team, sign a detailed service agreement, clarify devanning timeliness, service scope, and responsibility division, and avoid timeliness delays caused by agent operational errors.

Detail 3: Track Cargo Dynamics in Real Time and Maintain Information Transparency

Freight forwarders should use the shipping company's cargo tracking system to real-time grasp the navigation status, Estimated Time of Arrival (ETA), unloading progress, and devanning situation of the cargo after departing from Shanghai Port, and feedback the cargo dynamics to the customer every 24 hours. If there are routing adjustments, timeliness delays, or other situations, it is necessary to communicate with the customer in a timely manner, explain the reasons, and provide solutions to avoid customer complaints caused by information opacity and maintain their own professional reputation.

Conclusion: Flexible Routing Is the Key to Solving the Devanning Efficiency Problem of Shanghai to Los Angeles Ocean Freight

Currently, the congestion problem at LB Port is difficult to alleviate in the short term. To remain competitive in the Shanghai to Los Angeles ocean freight business, freight forwarders worldwide must abandon their reliance on a single route and establish a flexible routing planning system. By predicting port congestion trends in advance, cooperating with high-quality shipping companies and local agents, optimizing operational details, and establishing emergency plans, freight forwarders can not only effectively avoid LB Port congestion but also improve devanning efficiency and reduce operational costs. According to a report from Open PR on April 5, 2026, the current freight rate for a 40-foot container (FEU) from Shanghai to Los Angeles is about $2,663, a decrease of 1% month-on-month. In the context of declining freight rates, improving timeliness and service quality has become the core competitiveness of freight forwarders. In the future, with the evolution of the global maritime trade pattern and the optimization and upgrading of Los Angeles ports, freight forwarders also need to continuously pay attention to route dynamics and port policy changes, constantly optimize routing plans, and provide more efficient and stable Shanghai to Los Angeles ocean freight services for customers to achieve a win-win situation for themselves and their customers.
